Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Hudson Residents Choose Us for HeatShield Service
Corrine Halstead grew up in Queens, picked up her trade fundamentals at Apex Technical School in Long Island City, and has spent the better part of two decades working chimneys across central Massachusetts. She and our crew have cleaned and inspected systems throughout the region for years, including jobs in the older Colonial-era homes near Monument Square in Leominster where the flue liners tend to have stories of their own. That same eye for layered, multi-fuel chimney history is what we bring to Hudson.
We know the difference between a HeatShield Cerfractory coating that’s sound and one that’s hiding sulfur damage from a 1950s coal conversion. We stock HeatShield’s OEM Cerfractory sealant and SootEater rotary cleaning tools locally, so we’re not ordering parts while your chimney sits open. Every job starts with a camera scan, a written price, and a documented photo record - Clause 4 of the Haven Standard, running since 2009. Background-checked, uniformed technicians. License number on the page. A text when we’re on the way.
HeatShield sales & service is our specialty, but we’re independent - not affiliated with the manufacturer. That means we tell you when a HeatShield liner can be repaired and when it needs replacement, with no corporate playbook to follow.
Common HeatShield Chimney Cleaning Problems We Solve in Hudson
- Cerfractory coating delamination from coal-era sulfur residue. Hudson’s shoe-mill housing stock was built for coal, converted to oil, then adapted again for wood or pellet. That sulfur residue bonds to brick and reacts with HeatShield’s Cerfractory sealant, causing it to lift and flake. We find this in about one of every three pre-1925 chimneys we inspect in the downtown neighborhoods.
- Freeze-thaw cracking on exterior-wall chases. Hudson sits inland in Worcester County, and the temperature swings here are sharper than what you’d see closer to Boston. Water penetrates hairline cracks in HeatShield liners, freezes, expands, and widens the crack. By spring, you’ve got spalling. We see this pattern concentrated on north- and west-facing exterior walls.
- Assabet River corridor moisture attacking mortar crowns. The low-lying land near the riverbank holds humidity against chimney masonry. HeatShield mortar crowns soften, crumble, and let water behind the liner coating. The damage hides until the camera goes up. We’ve repointed crowns on Felton Street and Cox Street where efflorescence was the only visible warning.
- Overheating in mismatched multi-flue chases. In Hudson’s triple-deckers, one tenant installs a pellet insert in a flue sized for a coal furnace. The HeatShield-coated flue runs hotter than designed, the coating cracks, and creosote seeps into shared brick. The other flues keep venting, and nobody knows the masonry is deteriorating until backdraft pushes smoke into a second-floor unit.
- Class III glazed creosote in rarely-swept flues. When one unit in a two- or three-family gets cleaned and the others don’t, the neglected flue builds hard, tar-like creosote that standard brushes won’t touch. We use HeatShield’s SootEater rotary system to break it down, then evaluate whether the underlying liner can hold a new Cerfractory coat.

AfterHeatShield Service in Hudson: What Local Conditions Mean for Your Equipment
In Hudson’s triple-deckers and two-families near the old shoe-mill district, a single chimney chase often vents two or three separate flues for different units. When one tenant adds a pellet insert, only that flue gets cleaned while the shared masonry deteriorates unnoticed. This multi-flue, multi-unit pattern is rare in surrounding single-family suburbs like Stow or Bolton, and it changes everything about how HeatShield service needs to happen here.
We were called to a triple-decker on Felton Street after a tenant reported smoke backdraft from a pellet insert. Our tech found that only the third-floor flue had been swept in years, while the first-floor flue’s HeatShield coating had cracked and was allowing creosote to seep into the shared brick. We rodded and vacuumed all three flues, removed loose Cerfractory, re-coated the damaged sections with HeatShield, and repointed the crown to stop water intrusion. The job took a full day. The documentation - photos of all three flues, before and after, with written scope and price - ran to eight pages under Haven Standard Clause 4.
That kind of find is why we don’t price over the phone for Hudson’s mill-era housing. We need the camera in the flue first.

HeatShield Models & Products We Service in Hudson
We work with all HeatShield product lines: Cerfractory Flue Sealant for resurfacing sound brick flues, the 2000°F Flue Liner for high-heat wood and pellet applications, and the Universal Flue Liner for irregular or oversized chimneys. Our rotary cleaning uses HeatShield’s SootEater system, not generic brushes that can scar a Cerfractory coat.
For parts, we stock OEM HeatShield Cerfractory sealant and rotary tools. On dampers, caps, and flashing, we use corrosion-resistant aftermarket components that meet or exceed original specs - sourced through our buying network with DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield. Full replacement is our recommendation only when structural cracks or spalling make resurfacing unsafe. Otherwise, we repair. That stance has kept customers who use our Chimney Repair in Hudson from replacing liners that had five to ten years of service left.
HeatShield Service Pricing in Hudson
| Service | Price Range | What’s Included |
|---|---|---|
| Level 2 Inspection with camera scan | $180-$240 | Full flue video, photo record, written condition report |
| Rotary cleaning (SootEater) + inspection | $180-$290 | Creosote removal, debris vacuum, documentation |
| Cerfractory sealant touch-up | $220-$380 | Spot repair of delaminated or cracked coating |
| Full flue resurfacing | $280-$520 | Complete Cerfractory application, crown evaluation, photo record |
| Mortar repointing (crown or chase) | $340-$680 | Removal of spalled mortar, new pointing, water intrusion test |
What drives cost: flue length, number of flues in a shared chase, accessibility (steep roofs on triple-deckers add time), and the condition of existing HeatShield coating. Coal-era chimneys with sulfur damage need more prep. Freeze-thaw spalling may require repointing before any liner work can hold.
Every estimate is free, written, and delivered before work starts - Haven Standard Clause 1. No exceptions. Call (978) 481-2900 to schedule.

FAQs - HeatShield Chimney Cleaning in Hudson
Each flue needs its own inspection and cleaning schedule, regardless of what the neighbors do. NFPA 211 recommends annual inspection for all flues; wood-burning flues should be cleaned when creosote reaches 1/8 inch. In Hudson’s shared chases, we’ve found that cleaning one flue and ignoring the others lets moisture and creosote migrate through shared brick, damaging flues that looked fine from the outside. We inspect all flues in a chase and document each separately. Call (978) 481-2900 to book a multi-flue inspection - estimates are free.
Cracking that returns quickly usually means an underlying problem the coating can’t fix. In Hudson, the most common causes are exterior-wall freeze-thaw cycling (water gets behind the coating, freezes, and pushes it apart), mismatched flue sizing from a pellet insert retrofit (overheating), or moisture wicking up from a failed crown in the Assabet River corridor. A fresh Cerfractory coat over damaged brick is like paint over rot. We find the root cause with a camera scan, then quote the repair - not just the recoat. Call (978) 481-2900 and we’ll show you the footage.
Yes, and Hudson has hundreds of them. The challenge is that coal leaves sulfur residue in the brick that can react with modern sealants, and oil conversions often left flues oversized for today’s appliances. We use the SootEater rotary system to remove built-up deposits, test the brick for active sulfur with a moisture meter and visual inspection, and apply HeatShield Cerfractory only when the substrate is stable. When it’s not, we quote relining with a properly sized insulated liner. Every step is photographed and priced in writing before we start.
We do. We’re independent - not manufacturer-authorized - so we work on any HeatShield installation regardless of who did it. We bring the same process: camera scan first, written price, documented record. If the previous application was done without proper surface prep (we see this where Cerfractory was sprayed over glazed creosote), we’ll tell you exactly what failed and why. Free second opinion on any written estimate from another sweep.
Coal-era and converted-oil chimneys in Hudson typically need more inspection time and often more prep work than a clean, modern flue. Sulfur-damaged brick requires testing. Shared chases in triple-deckers mean accessing multiple flues, sometimes through different units. Freeze-thaw damage near the Assabet River can add crown repointing to what looked like a simple cleaning. Our pricing reflects actual conditions, not a flat rate that hides surprises. We put the scope and price in writing before any work starts - call (978) 481-2900 for your free estimate.
